If a reaction is exothermic, will the temperature always decrease? In not, what are the exceptions to this rule?

Exothermic/endothermic indicates a transfer of energy, but not always in the form of heat, so the temperature does not necessarily change.

^ yes it does not necessarily change, however you"ll see whether enthalpy is positive or negative by knowing if the reaction is exothermic or endothermic

Even though the temperature doesn't always change, knowing if the reaction is exothermic or endothermic helps indicate the enthalpy.
